The separate literatures on parental discipline, maternal discourse about e
motion, and autobiographical memory support the idea that parent-child disc
ourse in the context of a supportive relationship plays a role in a child's
early conscience development, and this study was designed to examine this
issue. Forty-two preschool children and their mothers took part in a 45-min
structured laboratory session, and at their homes, mothers completed the A
ttachment Q-Set. As part of the laboratory session, each mother was asked t
o discuss with her child one incident that occurred within the last week in
which her child behaved well and one in which her child misbehaved. These
conversations were transcribed verbatim and coded for maternal references t
o feelings, rules, consequences of the child's actions, and moral evaluativ
es. Each child also took part in a behavioral measure of internalization an
d several compliance tasks, and mothers completed a maternal report of the
child's early conscience development. Consistent with attachment theory, at
tachment security predicted maternal and child references to feelings and m
oral evaluatives. Attachment security, shared positive affect between the m
other and child, and maternal references to feelings and moral evaluatives
also predicted specific aspects of early conscience development.
